There aren't many actual ebay competitors (see ubid.com), but if you're just doing an all out product search here are some more useful tools: froogle.com, craigslist.org, pricegrabber.com, and there are many more like pricegrabber (search for comparison shopping). Though I would double check your product info and make sure you have everything right... Perhaps if you told us what it was we could help you find it.
